Lanxess, Hella launches new PBT compound for cars battery components




Lanxess AG in collaboration with Hella KGaA Hueck & Co has developed a new compound called Pocan AF4130.
It serves as a housing material for a battery management unit (BMU) and two cell monitoring units (CMU). The blend of polybutylene terephthalate (PBT) and acrylic ester-styrene-acrylonitrile (ASA) contains 30 percent by weight glass fibres and a halogen-based flame retardance package.
Hella fabricates the BMU and CMUs for a German manufacturer of battery systems for motor vehicles. The very flat devices currently are used in the lithium-ion battery system of a German compact car.
“The particular advantages of the material are its extremely low warpage and shrinkage, combined with its high flame retardance. We see great potential for application in precision components for vehicle battery systems,” said Marc Marbach, head of sales segments E&E in the Lanxess high performance materials (HPM) business unit.
